Fair enough.
BTW, I don't entirely buy your hardware complexity argument.
When we're looking at checksumming offload via 1's complement in the
RX descriptor, that is heaps simpler than having a seperate RTL path
for N different encapsulation technologies and/or protocols.
I'd rather maintain a single 1's complement circuit than N header
parser engines that trigger the sum at the right range.
There is definitely long term maintainability and stability value in
this.
